INSTALLATION Model RTD-7. 1) Mount the Reaction Time Delay unit away from heat, vibration & ignition wires. Fasten it with (4) #6 sheet metal screws, slightly compressing the rubbe; mounting grommets. It can be mounted in any position, even upside down for overhead locations. 2) Wire the unit as shown in the WIRING diagram. Use at least 14 gauge wire or larger. Install a fuse or circuit breaker to protect the box from possible damage. Make sure you have a good ground connection. (Grounding to the aluminum interior sheet metal is not reliable.) The "SAFETY SWITCH" (Bypass Switch) is supplied by Dedenbear. The RTD-7 has been specifically designed to operate at voltages up to 18 volts. You can now wire your unit directly to the 16 volt terminal if you are using a 16 VOLT BATTERY.

2 Do not power the RTD-7 and ignition with the same wire or battery cable, instead, run a seperate 12 aa. Power wire from the master "cut-off" switch at the back of the car directlv to the RTD-7. 3) The line lockterminal aHows you to lock the front wheel brakes without back-feeding and locking the trans brake during burn-outs. **If you don't want to connect the line-lock to your RTD, simply don't wire the "Line Lock" terminal. 4) As a safety device,the Reaction Time Delay has a circuit that cuts off power to the unit once the transbrake has been released. FOR ADDED SAFETY, THE SAFETY (Bypass) SWITCH SHOULD BE SET ON "NO DELAY" ANYTIME THAT. THE CAR IS NOT ON THE RACETRACK. The safety switch com~ktelvbv~assesthe reaction time deiav box so it can also be used as a backup switch in case you choose not to use the delay box. ** It selects either your button or the delay box to power the transbrake solenoid. 5) The safety switch also allows you to "bump" the car into the lights with the trans brake during staging, and "pro-brake".

3 Valve body transmissions can backup the vehicle in REVERSE . This means you won't have to wait for the delay to release each time you release the trans brake switch. ** NOTE: Safetv switch &controls the "Transbrake" terminal. The "Line Lock terminal (if used) will always delay whatever amount delay is programmed into the RTD. SEE REVERSE side FOR WIRING DIAGRAMS . - - OPERATtON. 1) Set the pushbutton thumbwheels to the desired delay setting. 2) Use your line lock button to do your burnout (if used). 3) If you need to engage the transbrake to back-up the car, do so with the safety switch set to "No Delay". 4) If you have a long delay dialed in and you stage by using the trans brake, then set the safety switch to "No Delay" and "bump" the car into the lights. After you are staged, hold the trans brake switch and flip the safety switch to "Delay". If you have a short delay setting, just use the trans brake switch to stage the car. 5) When the Christmas tree light that you are leaving off of turns on, release the trans brake switch.

4 After the dialed in delay time, the trans brake will release and launch the car. 6) ALWAYS SET THE SAFETY SWITCH TO "NO DELAY" WHENEVER THE CAR IS NOT ON THE TRACK READY TO. MAKE IT'S RUN. OR WHEN BACKING UP THE CAR WITH "PRO" BRAKE VALVEBODIES. TIPS ON SETTING THE DELAY. If you run on a Full tree, the time between lights is .500 seconds. Therefore, a perfect light is 500 (a Pro tree is .400) If you have a 472 light on a Full tree, leaving off the last amber, you need to set the time to 0028 (500-472=28 thousandths) , or if you leave off the top amber ( seconds). If your competitor is slower than yours & you leave off his top light, then add the handi- cap amount to your setting - : if his dial-in is &yours is , then your delay setting should be in the above example ( + second handicap). We recommend adding .010 or ,020 seconds as a cushion in case you stage deeper than normal. For a night race, add extra time because you see the lights turn on sooner than in the daytime.
